WZZerf/T'h aAefzfe/d BY ATTORNEYS Patented Get. 1, 1929 UNETEQ STATESPATENT @FFICE ALBERT F. WAKEFIELD, OF VERMILION, OHIO, ASSIGNOR To THEF. W. WAKEFIELD BRASS COMPANY, OF VERMILION, OHIO, A CORPORATION OF OHIOCEILING CANOPY AND EXTENSION The present invention relates to lightingfixture construction, and more particularly to suitable construction ofthe ceiling canopy and a detachable extension therefor particularlyadapted for use over exposed ceiling boxes and exposed ceihng conduits.Another object is the provision of a suitable mounting for the pullswitch mechanism where individual control of the light is desired. Tothe accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claim.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawing Fig. 1 is a vertical central section through thecanopy and extension; Fig. 2 is a fragmentary side elevation of aportion of the canopy and extension; Fig. 3 is another fragmentaryelevation of a portion of the canopy and extension; Fig. 4: is anelevational view of the switch mounting; and Fig. 5 is a perspectiveView of the switch mounting clip.

The present ceiling canopy and extension consists of a ceiling canopy 1of the usual inverted bell shape, having a vertical flange 2, with arolled edge 3, or the like. At the bottom the canopy terminates in aheavy an nular portion 4 through which slides the supporting tube 5,held in place by a set screw 6. A threaded nipple 7 is mounted in saidtube and is provided with a link union 8 at the bottom and anopen-sided, threaded union 9 at the top, the nipple being secured inplace by the union in the usual manner. The canopy also has a bushedaperture 12 near the bottom for the switch cord 10, and in the upperflange is provided with a punched knockout 11.

For use on a ceiling with exposed outlet boxes, or conduits, the canopyis supplied with a detachable extension 15 consisting of a sheet metalcylinder adapted to fit snugly within the vertical flange 2 of thecanopy, as

best shown in Fig. 1. This canopy is provided withan aperture 16 nearthelower edge adapted to bealigned with the knockout 11 in the flange 2.The canopy is also provided with a series ofv twist-outs 17 cut throughthe metal to provide openings for exposed conduits or wiring, thesetwist-outs being spaced at 90 degrees about the extension and threebeing provided. Below the twist-outs are a second series of double-cutsemi-circular twist-outs 18 for conduits, or the like, and these arespaced about the extension, as are'the twist-outs 17, so as to providefor wiring in three directions if neces-- sary.

The canopy and extension also provide room for the mounting of a pullswitch20, having the usual switch cord 10, this switch being supportedon the tube 5 by means of a supporting clip 21 of special design. Asbest shown in Fig. 5, such clips consist of a piece of sheet metalhaving a horizontal ear 22, with an aperture 28 adapted to be clampedbetween the top of the tube 5 and the union 9, (see Figs. 1 and 4E), anda second ear 24 that lies in a plane at right angles to that of the ear22 and is furthermore twisted through a similar angle, so as to beofiset from said ear 22, as well. Ear 2 1 likewise has an aperture 25adapted to fit over the threaded extension 26 of the switch to which itis clamped by a nut 27 so that the switch is held with the extensions 26and the operating end 28 in the desired horizontal position. Theopenings 28 and 25 will preferably be made of approximately the samediameter so that the clip may be secured by either ear to the top oftube 5 and the switch then attached to the other car. It will further benoted that the openings in question are located at different distancesfrom the adjacent edges of the two ears, so that by thus variouslyassembling the clip in the fixture, a corresponding variation can begiven to the positionof the switch and thus best accommodate it to thespace available within the latter.

The present extension and ceiling canopy construction make the unitquickly adaptable to meet all building conditions whether the wiring isconcealed or exposed and whether the outlet boxes are exposed or sunk inthe ceiling. It provides easily opened apertures for the necessary wiresor conduits and is securely clamped in place as the connecting unionholds it tightly against the ceiling and against the canopy. Theextension will of course be finished in the same color as the canopy,and thus when used gives the appearance of a unitary structure. It isinexpensive to manufacture, being referably a sheet of metal formed intoa cy inder with the overlapping ends secured together by eyelets 80,

or the like.

The device is particularly adaptable for use with fixtures where theyare sold to meet commercial requirements as a single fixture unit andcanopyemay thus be adapted to all normal conditions.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change beingmade as regards the mechanismherein disclosed, provided the means stated by the following claim orthe equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my-invention:-

I11 a ceiling canopy construction, the combinationof an inverted bellshaped canopy having a tube therein, a nipple extending through saidtube and having a chain link at the bottom and a threaded union at thetop, and a switch support clip adapted to be clamped between said tubeand said union to support a switch within saidcanopy, said clipcomprising two 'angularly related ears, substantially as described.

Signed by me, this 21st day of August, 1924 ALBERT F..WAKEFIELD.
